Specification of Letters Patent.

Patented Dec. 31, 1907.

Application filed June 10. 1905, Serial No 264.560.

To all whom it may concern:

New Rochelle, county of Westchester, State or New York, have invented certain new and useful Improvements in Methods of Making Silicon Cal-bid, of which the following is a .I have discovered a new reaction for producing silicon carbid,nen1ely SiO +20 SiC+ COQ The reaction is accomplished by mixing the materials preferably in e fine state of subdivision and heatin them sufficiently, referably in a suitable e, ectric furnace, in t e ab sence of free or'ygen or other reactive gas.

Efeieim as my invention:

i l The method of producingsiiicon carbid by heating together one equivalent of silicon monoxici end'two equivalents of carbon.

2. T liemethod of producing silicon carbid, which consists in heating a mixture of silicon monoxid and carbon in approximately the proportions of one equivalent of silicon monoXid to two equivalents of carbon.

Signed at New York, in the county of New York, and State of New York, this 7th dayof June A. D. 1905 HENRY NO L. POTTER.
